There are (3) Key Topics associated with a 'Slow Flushing Toilet': (1) 'Adjusting the Toilet Tank Water Level' covers a low water supply in the toilet tank. (2) Older toilets and houses with hard water can get a sediment build up in the water inlet. 'Cleaning Out Toilet Sediment' covers this issue. (3) 'Removing Toilet Blockages' talks about partially blocked toilets that will flush slowly.
Toilets are engineered to use a certain amount of water to flush. When the water rushes into the bowl, it creates a siphon that removes the waste and rinses the bowl. Too little water or water that gets there too slow can cause the toilet to flush poorly.
Water Usage for Toilets
Toilets that used a large supply of water would be prone to slow flushes. Hard water and sediment can also be a factor.
A toilet that flushes slowly can be very annoying. When a toilet does not flush properly, clogs are frequent. A clogged toilet is more than irritating. The dirty messy water is no fun and can be a health hazard.
In the mid nineties, toilets had to start using 1.6 gallons of water per flush. Prior to that time toilets could use 3.5 to as high as 7 gallons of water. The design of toilet would require that the full amount be used. In an effort to conserve, some homeowners would adjust the water level down. This will cause the toilet to flush slowly, since there is not enough water pressure to create the proper siphon effect.

Were you able to deal with your slow flushing toilet? It may have been as simple as adjusting the float. This is especially true for older toilets. In years gone by, toilets needed a lot of water to flush properly. When the tank level gets too low, the proper siphoning will not start.
Another common problem is sediment in the inlet valve. Again, older toilets are more likely to have this trouble. Then there is the 'object' stuck in the trap.
